Diesel Emissions Applications

A new EC regulation states that diesel engines need to have active cleaning with urea injection in order to reduce NOx emissions. In order to control the urea dosage, a reliable measurement system is required. OPSIS LD500 laser diode gas analyser for monitoring ammonia (NH3), has been tested and approved by German TÜV, in accordance with the EURO VI standard.

Ironically, transit facilities such as airports, bus stations, and train stations are threatened by vehicle exhaust, road dust, crowds of people, and high levels of traffic. The soot from diesel exhausts consists of tiny particles that get caught in lungs and can cause health problems. Partially burned fuels contain carcinogenic hydrocarbons. Inside airports, for example, there are food courts, round-the-clock cleaning operations, and outside air pollution entering with the ventilation air. Some airports have...

The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the InfraCal 2 Ethanol Blend Analyzer shown in the photo, can help fuel blenders quickly flag out-of-spec...

For PM emission control in high temperature exhaust streams, such as fuel oil boilers, usual dedusters such as bag filters are very maintenance demanding. Particularly, diesel and fuel particulates are very sticky and clog to filter elements, unless protection reagents are used. Flue gas cooling is also needed in front of the filter when temperatures are higher than 200 ºC. On the other hand, regular cyclones and multicyclones are frequently not able to reduce emissions to present emission limits.

PLAZKAT Aero systems are used to treat emissions from motor and railroad vehicles. It has been found that exhaust gases from internal combustion engines (ICE) contain over 250 ingredients. Major components include carbon oxides, nitrogen oxides and hydrocarbons.

Control of ship diesel engine emissions to meet MARPOL requirements for particulate ash and soot, sulfur dioxide and NOx. Special compact inline stack mounted space saving designs. Both open loop arrangements using sea water or closed loop using a range of chemical solutions. Complete system offerings.

Facilitates Data Management for Tank Emissions Reporting; VisionMonitor Software leverages existing technology investments you have deployed to run your current operations. It simplifies the process of gathering tank inventory data by linking to existing internal systems, automating data collection from these systems via a scheduler, and by providing a path for manual input when required for sources such as diesel engines, package boilers, etc.
